Alien Invasyndrome Laboratory and Cafeteria Route

Route scope

This walkthrough covers Laboratory + Cafeteria as a landmark risk route on Atlas Middle deck in the Alien Invasyndrome Steam Demo. It sits between Clinic Doctor Route comfort and Security Routes commitment. This is not a promise of full-release map completeness — only Demo-verified landmarks and habits.

All characters are 18+. Adult scenes may appear in adjacent rooms; this page mentions them only as progression timing, never as graphic detail.

Developer Mozu Field / 百舌鳥, publisher Shady Corner Games, Steam app 4603980. Full release TBA. Latest public Demo: 1.0 hotfix (May 2026) — no newer numbered Demo confirmed. Hub: Walkthrough Hub. Map siblings: Key Rooms, Middle Deck Loop.

walkthrough and secret places

When to open this route

Open Lab & Cafeteria when:

1. Kitchen Route softlocks feel automatic.
2. Clinic first-meeting pacing is done or intentionally skipped today — Clinic Doctor Route.
3. Nest progress is banking — How to Nest, Nest Checklist.
4. You accept optional risk — Security remains the Demo gate, not Laboratory tourism.
5. Detection recovery is practiced — Stealth and Detection.

Do not open this route on your first Atlas hour. Learn How to Play and Kitchen first.

Pre-route checklist

• One nest bank completed this session
• Three-cover rule named: scout / commit / exit — Vents and Cover
• Detection Timer ready — Detection Timer
• Softlock Fixes bookmarked — Softlock Fixes
• Crew idle cycles skimmed — Crew
• Security Routes pre-read so you know when to stop sightseeing

Phase 1 — Cafeteria as crossing, not camp

Cafeteria is a traffic hub with wide sight lines. Treat it as a wall-line transit, not a nest home.

1. Enter along the shadow edge you scouted from Kitchen-adjacent corridors.
2. Cross during far-table idle moments; never diagonal through open seating mid-turn.
3. Pre-select abort: return the way you entered if a cone snaps toward you.
4. Zero commits on the first crossing — this phase is landmark literacy only.

Cafeteria fails when players camp tables like Kitchen desks. Kitchen has tighter loops; Cafeteria punishes center-floor greed. Room dossier: Key Rooms Cafeteria section.

If spotted in Cafeteria, softlock only at furniture with a verified exit. Wide floors make panic sprints lethal.

Phase 2 — Laboratory scout (two passes, zero greed)

Laboratory is Clinic’s stricter sibling: longer reads, more visual clutter, same desk softlock risk.

Before any Laboratory interact:

1. Scout the doorway twice — Laboratory re-entries surprise players who stare at the wrong prop.
2. Confirm desk / furniture softlock with exit geometry tested, not assumed.
3. Confirm an exit vector different from entry.
4. Still do not commit unless today’s goal is a single probe.

Laboratory is where early build starts to matter. If captures feel impossible without suicidal peeks, pause at Early Build and Skill Tree before forcing this wing.

Phase 3 — Single-objective commit

When the gap is real and nest is healthy:

1. Move during the blind arc.
2. Touch one objective — interact, capture window, or route tag.
3. Softlock immediately if aggro spikes.
4. Wait the full ~1 minute if fully spotted.
5. Exit to cover before the next sweep.

Do not chain Laboratory into Cafeteria recross without banking. Two-room greed is how Security later feels impossible.

Capture discipline: How to Capture applies the same quiet standard here.

Phase 4 — Nest banking stop rule

After any clean Lab or Cafeteria slice:

1. Exit to a safer Middle junction — Decks.
2. Bank nest progress immediately.
3. Optional skill spend via Skill Planner.
4. Decide: stop for today, Middle Deck Loop practice, or Security prep.

Hard stop rule: if detection spiraled once, bank and abort. Do not “finish Lab because you are already here.”

Phase 5 — Exit toward Security or abort

You may leave this route for Security only when:

• Nest economy is stable after Lab/Cafeteria gains.
• Softlock recovery is boring, not heroic.
• You picked Security Way A or Way B in advance — Security Routes, Security Room.
• You are not mid-detection penalty.

Boss comes after Security, not after Laboratory pride — Boss Route, How to Beat the Boss.

Desk softlocks on this route

Laboratory and Cafeteria share Atlas desk logic with Clinic and Kitchen:

• Intended hide: wait, then exit after timer mood settles.
• Stuck state: UI dead, cannot leave — Softlock Fixes.

Laboratory desks are especially rude: exits look obvious yet collision-block in Demo builds. Pre-check stand-up timing so you do not pop into a facing cone.

Inputs: Stealth Actions, Keyboard. Locale: Locale Emulator.

Failure modes on this route

Failure	Likely cause	Fix
Spotted in Cafeteria center	Open-floor cross	Wall-line transit only
Laboratory re-entry surprise	One-pass scout	Repeat Phase 2 twice
Desk trap	No exit geometry test	Pre-check furniture
Security wipe later	Skipped bank stop	Force Phase 4
Unreadable prompts	Locale	Locale Emulator
Empty power curve	Nest starvation	How to Nest
Map confusion	Deck literacy gap	Atlas Overview

Session script (20–30 minutes)

1. Kitchen warm-up softlock — Kitchen Route.
2. Nest bank once.
3. Cafeteria wall-line cross (no commit).
4. Laboratory two-pass scout + optional one objective.
5. Bank again.
6. Stop or pivot to Security — not both Lab greed and Security same hour if messy.
